I think nobody cannot know the answer of your question.Give a chance to ticket and send it to Reto.Probably they don't answer it too.
I suggest:
Close all applications when you are playing online games.Check out Task Manager for be sure.
Only your device should be connected to your modem
Join an Asia server in different game for be sure about your minimum ping value
Also you can test your ping value in this site: http://beta.speedtest.net/

No,community can't translate H&G for now.
Maybe Reto will allow it in future.
If they allow game's community for translate the game to Lithvanian language if you haven't got a interpreter certificate,you can't do it my friend.
